总的模块的开发：

简单介绍一下大型电商网站架构：

 

系统构建：

第一天：

环境搭建：

 

 

 

 

 

安装java环境：

注：这里可以百度一下 jdk的环境变量的配置。

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Windows的FTP安装完成

 

 

数据表结构的设计：

 

 

第一天：开始创建maven项目：

 

 

Java是sourceRoot（自己创建）

Test自己创建

对应的sourcesRoot

 

项目的整体架构如下图所示：

配置maven的pom文件

Pom:

包的结构：

 

在common中编写常用的类，四个：

第一个Const

package com.mmall.common;

import com.google.common.collect.Sets;

import java.util.Set;

/**
 * Created by geely
 */
public class Const {

    public static final String CURRENT_USER = "currentUser";

    public static final String EMAIL = "email";
    public static final String USERNAME = "username";

    public interface ProductListOrderBy{
        Set<String> PRICE_ASC_DESC = Sets.newHashSet("price_desc","price_asc");
    }

    public interface Cart{
        int CHECKED = 1;//即购物车选中状态
        int UN_CHECKED = 0;//购物车中未选中状态

        String LIMIT_NUM_FAIL = "LIMIT_NUM_FAIL";
        String LIMIT_NUM_SUCCESS = "LIMIT_NUM_SUCCESS";
    }

    public interface Role{
        int ROLE_CUSTOMER = 0; //普通用户
        int ROLE_ADMIN = 1;//管理员
    }

    public enum ProductStatusEnum{
        ON_SALE(1,"在线");
        private String value;
        private int code;
        ProductStatusEnum(int code,String value){
            this.code = code;
            this.value = value;
        }

        public String getValue() {
            return value;
        }

        public int getCode() {
            return code;
        }
    }


    public enum OrderStatusEnum{
        CANCELED(0,"已取消"),
        NO_PAY(10,"未支付"),
        PAID(20,"已付款"),
        SHIPPED(40,"已发货"),
        ORDER_SUCCESS(50,"订单完成"),
        ORDER_CLOSE(60,"订单关闭");


        OrderStatusEnum(int code,String value){
            this.code = code;
            this.value = value;
        }
        private String value;
        private int code;

        public String getValue() {
            return value;
        }

        public int getCode() {
            return code;
        }

        public static OrderStatusEnum codeOf(int code){
            for(OrderStatusEnum orderStatusEnum : values()){
                if(orderStatusEnum.getCode() == code){
                    return orderStatusEnum;
                }
            }
            throw new RuntimeException("么有找到对应的枚举");
        }
    }
    public interface  AlipayCallback{
        String TRADE_STATUS_WAIT_BUYER_PAY = "WAIT_BUYER_PAY";
        String TRADE_STATUS_TRADE_SUCCESS = "TRADE_SUCCESS";

        String RESPONSE_SUCCESS = "success";
        String RESPONSE_FAILED = "failed";
    }



    public enum PayPlatformEnum{
        ALIPAY(1,"支付宝");

        PayPlatformEnum(int code,String value){
            this.code = code;
            this.value = value;
        }
        private String value;
        private int code;

        public String getValue() {
            return value;
        }

        public int getCode() {
            return code;
        }
    }

    public enum PaymentTypeEnum{
        ONLINE_PAY(1,"在线支付");

        PaymentTypeEnum(int code,String value){
            this.code = code;
            this.value = value;
        }
        private String value;
        private int code;

        public String getValue() {
            return value;
        }

        public int getCode() {
            return code;
        }


        public static PaymentTypeEnum codeOf(int code){
            for(PaymentTypeEnum paymentTypeEnum : values()){
                if(paymentTypeEnum.getCode() == code){
                    return paymentTypeEnum;
                }
            }
            throw new RuntimeException("么有找到对应的枚举");
        }

    }




}

第二个ResponseCode编码响应的状态：

package com.mmall.common;



/**

 * Created by geely

 */

public enum ResponseCode {



    SUCCESS(0,"SUCCESS"),

    ERROR(1,"ERROR"),

    NEED_LOGIN(10,"NEED_LOGIN"),

    ILLEGAL_ARGUMENT(2,"ILLEGAL_ARGUMENT");



    private final int code;

    private final String desc;





    ResponseCode(int code,String desc){

        this.code = code;

        this.desc = desc;

    }



    public int getCode(){

        return code;

    }

    public String getDesc(){

        return desc;

    }



}

第三个ServerResponse

package com.mmall.common;



import org.codehaus.jackson.annotate.JsonIgnore;

import org.codehaus.jackson.map.annotate.JsonSerialize;



import java.io.Serializable;



/**

 * Created by geely

 */

@JsonSerialize(include =  JsonSerialize.Inclusion.NON_NULL)

//保证序列化json的时候,如果是null的对象,key也会消失

public class ServerResponse<T> implements Serializable {



    private int status;

    private String msg;

    private T data;



    private ServerResponse(int status){

        this.status = status;

    }

    private ServerResponse(int status,T data){

        this.status = status;

        this.data = data;

    }



    private ServerResponse(int status,String msg,T data){

        this.status = status;

        this.msg = msg;

        this.data = data;

    }



    private ServerResponse(int status,String msg){

        this.status = status;

        this.msg = msg;

    }



    @JsonIgnore

    //使之不在json序列化结果当中

    public boolean isSuccess(){

        return this.status == ResponseCode.SUCCESS.getCode();

    }



    public int getStatus(){

        return status;

    }

    public T getData(){

        return data;

    }

    public String getMsg(){

        return msg;

    }





    public static <T> ServerResponse<T> createBySuccess(){

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode());

    }



    public static <T> ServerResponse<T> createBySuccessMessage(String msg){

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode(),msg);

    }



    public static <T> ServerResponse<T> createBySuccess(T data){

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode(),data);

    }



    public static <T> ServerResponse<T> createBySuccess(String msg,T data){

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode(),msg,data);

    }





    public static <T> ServerResponse<T> createByError(){

        return new ServerResponse<T>(ResponseCode.ERROR.getCode(),ResponseCode.ERROR.getDesc());

    }





    public static <T> ServerResponse<T> createByErrorMessage(String errorMessage){

        return new ServerResponse<T>(ResponseCode.ERROR.getCode(),errorMessage);

    }



    public static <T> ServerResponse<T> createByErrorCodeMessage(int errorCode,String errorMessage){

        return new ServerResponse<T>(errorCode,errorMessage);

    }



























}

第四个TokenCache:

package com.mmall.common;



import com.google.common.cache.CacheBuilder;

import com.google.common.cache.CacheLoader;

import com.google.common.cache.LoadingCache;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;



import java.util.concurrent.TimeUnit;



/**

 * Created by geely

 */

public class TokenCache {



    private static Logger logger = LoggerFactory.getLogger(TokenCache.class);



    public static final String TOKEN_PREFIX = "token_";



    //LRU算法

    private static LoadingCache<String,String> localCache = CacheBuilder.newBuilder().initialCapacity(1000).maximumSize(10000).expireAfterAccess(12, TimeUnit.HOURS)

            .build(new CacheLoader<String, String>() {

                //默认的数据加载实现,当调用get取值的时候,如果key没有对应的值,就调用这个方法进行加载.

                @Override

                public String load(String s) throws Exception {

                    return "null";

                }

            });



    public static void setKey(String key,String value){

        localCache.put(key,value);

    }



    public static String getKey(String key){

        String value = null;

        try {

            value = localCache.get(key);

            if("null".equals(value)){

                return null;

            }

            return value;

        }catch (Exception e){

            logger.error("localCache get error",e);

        }

        return null;

    }

}

Day01

包的结构：

 

在common中编写常用的类，四个：

第一个Const

package com.mmall.common;

import com.google.common.collect.Sets;

import java.util.Set;

/**
 * Created by geely
 */
public class Const {

    public static final String CURRENT_USER = "currentUser";

    public static final String EMAIL = "email";
    public static final String USERNAME = "username";

    public interface ProductListOrderBy{
        Set<String> PRICE_ASC_DESC = Sets.newHashSet("price_desc","price_asc");
    }

    public interface Cart{
        int CHECKED = 1;//即购物车选中状态
        int UN_CHECKED = 0;//购物车中未选中状态

        String LIMIT_NUM_FAIL = "LIMIT_NUM_FAIL";
        String LIMIT_NUM_SUCCESS = "LIMIT_NUM_SUCCESS";
    }

    public interface Role{
        int ROLE_CUSTOMER = 0; //普通用户
        int ROLE_ADMIN = 1;//管理员
    }

    public enum ProductStatusEnum{
        ON_SALE(1,"在线");
        private String value;
        private int code;
        ProductStatusEnum(int code,String value){
            this.code = code;
            this.value = value;
        }

        public String getValue() {
            return value;
        }

        public int getCode() {
            return code;
        }
    }


    public enum OrderStatusEnum{
        CANCELED(0,"已取消"),
        NO_PAY(10,"未支付"),
        PAID(20,"已付款"),
        SHIPPED(40,"已发货"),
        ORDER_SUCCESS(50,"订单完成"),
        ORDER_CLOSE(60,"订单关闭");


        OrderStatusEnum(int code,String value){
            this.code = code;
            this.value = value;
        }
        private String value;
        private int code;

        public String getValue() {
            return value;
        }

        public int getCode() {
            return code;
        }

        public static OrderStatusEnum codeOf(int code){
            for(OrderStatusEnum orderStatusEnum : values()){
                if(orderStatusEnum.getCode() == code){
                    return orderStatusEnum;
                }
            }
            throw new RuntimeException("么有找到对应的枚举");
        }
    }
    public interface  AlipayCallback{
        String TRADE_STATUS_WAIT_BUYER_PAY = "WAIT_BUYER_PAY";
        String TRADE_STATUS_TRADE_SUCCESS = "TRADE_SUCCESS";

        String RESPONSE_SUCCESS = "success";
        String RESPONSE_FAILED = "failed";
    }



    public enum PayPlatformEnum{
        ALIPAY(1,"支付宝");

        PayPlatformEnum(int code,String value){
            this.code = code;
            this.value = value;
        }
        private String value;
        private int code;

        public String getValue() {
            return value;
        }

        public int getCode() {
            return code;
        }
    }

    public enum PaymentTypeEnum{
        ONLINE_PAY(1,"在线支付");

        PaymentTypeEnum(int code,String value){
            this.code = code;
            this.value = value;
        }
        private String value;
        private int code;

        public String getValue() {
            return value;
        }

        public int getCode() {
            return code;
        }


        public static PaymentTypeEnum codeOf(int code){
            for(PaymentTypeEnum paymentTypeEnum : values()){
                if(paymentTypeEnum.getCode() == code){
                    return paymentTypeEnum;
                }
            }
            throw new RuntimeException("么有找到对应的枚举");
        }

    }




}

第二个ResponseCode编码响应的状态：

package com.mmall.common;



/**

 * Created by geely

 */

public enum ResponseCode {



    SUCCESS(0,"SUCCESS"),

    ERROR(1,"ERROR"),

    NEED_LOGIN(10,"NEED_LOGIN"),

    ILLEGAL_ARGUMENT(2,"ILLEGAL_ARGUMENT");



    private final int code;

    private final String desc;





    ResponseCode(int code,String desc){

        this.code = code;

        this.desc = desc;

    }



    public int getCode(){

        return code;

    }

    public String getDesc(){

        return desc;

    }



}

第三个ServerResponse

package com.mmall.common;



import org.codehaus.jackson.annotate.JsonIgnore;

import org.codehaus.jackson.map.annotate.JsonSerialize;



import java.io.Serializable;



/**

 * Created by geely

 */

@JsonSerialize(include =  JsonSerialize.Inclusion.NON_NULL)

//保证序列化json的时候,如果是null的对象,key也会消失

public class ServerResponse<T> implements Serializable {



    private int status;

    private String msg;

    private T data;



    private ServerResponse(int status){

        this.status = status;

    }

    private ServerResponse(int status,T data){

        this.status = status;

        this.data = data;

    }



    private ServerResponse(int status,String msg,T data){

        this.status = status;

        this.msg = msg;

        this.data = data;

    }



    private ServerResponse(int status,String msg){

        this.status = status;

        this.msg = msg;

    }



    @JsonIgnore

    //使之不在json序列化结果当中

    public boolean isSuccess(){

        return this.status == ResponseCode.SUCCESS.getCode();

    }



    public int getStatus(){

        return status;

    }

    public T getData(){

        return data;

    }

    public String getMsg(){

        return msg;

    }





    public static <T> ServerResponse<T> createBySuccess(){

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode());

    }



    public static <T> ServerResponse<T> createBySuccessMessage(String msg){

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode(),msg);

    }



    public static <T> ServerResponse<T> createBySuccess(T data){

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode(),data);

    }



    public static <T> ServerResponse<T> createBySuccess(String msg,T data){

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode(),msg,data);

    }





    public static <T> ServerResponse<T> createByError(){

        return new ServerResponse<T>(ResponseCode.ERROR.getCode(),ResponseCode.ERROR.getDesc());

    }





    public static <T> ServerResponse<T> createByErrorMessage(String errorMessage){

        return new ServerResponse<T>(ResponseCode.ERROR.getCode(),errorMessage);

    }



    public static <T> ServerResponse<T> createByErrorCodeMessage(int errorCode,String errorMessage){

        return new ServerResponse<T>(errorCode,errorMessage);

    }



























}

第四个TokenCache:

package com.mmall.common;



import com.google.common.cache.CacheBuilder;

import com.google.common.cache.CacheLoader;

import com.google.common.cache.LoadingCache;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;



import java.util.concurrent.TimeUnit;



/**

 * Created by geely

 */

public class TokenCache {



    private static Logger logger = LoggerFactory.getLogger(TokenCache.class);



    public static final String TOKEN_PREFIX = "token_";



    //LRU算法

    private static LoadingCache<String,String> localCache = CacheBuilder.newBuilder().initialCapacity(1000).maximumSize(10000).expireAfterAccess(12, TimeUnit.HOURS)

            .build(new CacheLoader<String, String>() {

                //默认的数据加载实现,当调用get取值的时候,如果key没有对应的值,就调用这个方法进行加载.

                @Override

                public String load(String s) throws Exception {

                    return "null";

                }

            });



    public static void setKey(String key,String value){

        localCache.put(key,value);

    }



    public static String getKey(String key){

        String value = null;

        try {

            value = localCache.get(key);

            if("null".equals(value)){

                return null;

            }

            return value;

        }catch (Exception e){

            logger.error("localCache get error",e);

        }

        return null;

    }

}
